Whoever said Siam (Bor Kei Mee Karn Pua Pun Kub LanXang) that person need to go back to retrain or reschooling in History again...and that person need to talk to Sujitvongthed one of the best historian in Thailand.
Lao and Thai official histories have many commonalities Official Lao history is mostly propaganda and official Thai history is propaganda served with excessive imaginations. Lao history is used only to legitimize its current one-party dominated political structure while Thai history composes mainly of narratives about kings, and their exploit in wars so to sacralize the monarchy.
